Comparison
Lift or replace? Polyjacking vs new concrete
Lifting can be a practical alternative to replacement — but only when the concrete itself is worth keeping.
Side-by-side
| Lifting | Replacement | |
|---|---|---|
| Best for | Intact slabs that settled | Deteriorated, broken or heaved concrete |
| Disruption | Small holes; no demolition | Demolition, forming, pouring, curing |
| Appearance | Existing surface and cracks remain | New surface |
| Sub-base | Voids filled beneath existing slab | Opportunity to rebuild base properly |
| Cost | Depends on job | Depends on job |
Choose replacement when
- Concrete is crumbling, spalled or shattered
- The slab has heaved
- You want a new appearance or layout
- The sub-base needs complete rebuilding
Next step: an assessment
Photos help, but the only reliable way to decide whether a slab can be lifted is an on-site look at the concrete, the drainage and the likely cause of settlement. Submit a request and the HAUSE intake team will review it and confirm whether a suitable contractor is available in your area.
